Twenty-odd years before Newton stated the three laws of motion, he conducted a simple, breakthrough prism experiment. He poked a hole through his window shade, allowing a single beam of light to shine through. Placing a prism in the light’s path, he broke the beam into its color spectrum. If light were composed of a rainbow of colors, he reasoned, he should be able to recombine them into white sunlight by passing them through a lens and a second prism. He was right.

and the importance of driving innovation, and yet few people want to
change what they are doing? This is the first paradox of innovation.
For most people, innovation means others doing things differently.
